no reason for him to retire, he got caught by a good one and it was a brutal KO but thats part of boxing. he was fighting well until he got caught so he still got it, if he should have retired it should have been a few fights ago but now he has something to prove.
he cant go out like this, he should atleast try to avenge the loss to marquez. then set things straight with bradley and if a mayweather fight cant be made have one last farewell fight in the phillipines. but he cant go out like this, especially when theres no need to, he can still fight. crazy how one punch can make ppl forget that, i get his family but everyone else.
